TREND OF CARDIOVASCULAR RISK-FACTORS IN THE EAST-GERMAN POPULATION 1968-1992

The deteriorating trend of life expectancy since the mid 1970s, mainly due to higher cardiovascular mortality in the East compared to West G ermany, requires explanations about what happened to the cardiovascula r risk factor profile in the East. Epidemiologic studies in the East G erman population have been performed for about 25 years and can justif y a first answer to the question, whether the opening gap in life expe ctancy could be attributable to a deteriorating cardiovascular risk fa ctor profile of the 25-64 year old population. During a review process reliable epidemiological studies in the East German population have b een identified to describe sequential changes from 1968 to 1992 in sys tolic and diastolic blood pressure (SBP, DBP) total cholesterol (CHOL) , body mass index (BMI) and cigarette smoking in five periods of time. The mean SBP increased in males of higher age groups, whereas it drop ped in females in all age groups in this period of time. The mean CHOL showed a striking increase in both sexes and levelled off in the mid 1980s only. The mean BMI increased slightly in men of the middle age g roups and remained almost unchanged in women. The prevalence of cigare tte smoking increased in both sexes until the 1970s, and declined ther eafter in the age groups over 40, however, there is an increasing tend ency in young age groups and females after the wall came down. These t rends are congruent with the hypothesis, that the increasingly unfavou rable trend of life expectancy in East Germany (compared to the contin uously improving trend in West Germany) is at least partly attributabl e to the trend of the cardiovascular risk factor profile.
